I deleted my only launcher and now I cannot open settings to set to debug mode in order to use ADB or similar to install a new launcher. I can't open the Play store, can't open anything except those that use voice commands: e-mail, text, phone, maps, navigation, and note to self.

Download the Launcher .apk file (just Google your "demand launcher name" and plus "apk"), save it to your friend's phone, and send it to your phone via Bluetooth. After you recieve the .apk file just click whatever option that directs you to INSTALL the file. If Bluetooth is off, ask your friend to call your phone; when the dialer window pops up you can see a "make another call" button. Click it and you will see the shortcut bar for Bluetooth appear.

Go into Recovery Mode (try turning off the phone and do not turn it on but press and hold the home button the volume up button and then hold the power button along with it). You need to do a Factory Reset from there and then reboot the phone.
